Ender 3 Pen holder for plotter

*I made the spring a bit harder to press so that the pen doesn't wobble around too much, added a M3 nut housing to make the screwing easier.

This is a part to add to the Ender 3 Hero Me gen2 fanduct. it screws in place where the leveling sensor should go and it can stay attached even when not in use.

You can add a pen to it and tighten it up with the screw, you need an M3 bolt and nut to fix the pen and to fix the printed part you can reuse the stock screws.
